I can’t imagine having to raise 3 geniuses! How would you ever win an argument? Had that problem with my son and he’s very smart but don’t think he’s a genius.
I figured that if my son could come up with a good reason for something that I had to consider it. “Because I said so” didn’t work all that well. :-)
Moral relativism would not fly here. Faith actually would. Brilliance clothed in sound faith is great wisdom.
